As others have mentioned, the primary issue here are the hardware requirements for Windows 11. The result are millions of PCs (I guess, definitely a lot though) that are fully functional from a technical point of view, but cannot run Windows 11 and should not run any other Windows due to the security implications of running unpatched software.
They are a lot more likely to think about Windows, as they actively decided to avoid using it by moving to Linux. That is in stark contrast to the subset of Windows users that would never give it a second thought, as they are unaware of what an operating system even is, nevermind having an overview of which ones exist and what their respective advantages may be.
